Tweetsharp SendTweetWithMedia from url

Question

I am trying to use Tweetsharp's SendTweetWithMedia with a image which I don't have stored locally, I only have a url. All the examples I have found of SendTweetWithMedia use a file on the local system.

var thumb = "http://somesite.net/imageurl";
var service = new TwitterService(key, secret);
service.AuthenticateWith(token, tokenSecret);
var req = WebRequest.Create(thumb);
using (var stream = req.GetResponse().GetResponseStream())
{
    response = service.SendTweetWithMedia(new SendTweetWithMediaOptions
    {
    Status = tweet.Trim(),
    Images = new Dictionary<string, Stream> { { fullname, stream } }
    });
}

I get the following error from SendTweetWithMedia:

'System.NotSupportedException': This stream does not support seek operations.

I could download the file from the url and save locally, but I'd rather use the url. Is this possible?

You can check with reading stream and storing it to memory stream like this in accepted answer : http://stackoverflow.com/questions/3434007/error-this-stream-does-not-support-seek-operations-in-c-sharp — Akash KC, Feb 01 '17 at 22:13
Thanks I tried using a memory stream and it did get further. However SendTweetWithMedia just times out and returns null after about 1 minute. To be honest I might as well download the url and save to a local file as convert everything to a MemoryStream. At least I'd be then on the familiar ground everyone else seems to be using. — Rob Sedgwick, Feb 01 '17 at 23:12

In the end, I just created a temporary file:

byte[] data;
using (var client = new WebClient())
{
    data = client.DownloadData(thumb);
}
File.WriteAllBytes($"{Path.GetTempPath()}\\xyz.jpg", data);

best answer I could come up with. Still a few more lines than I'd like though.
